Promax HF-2 BMX crank set

The HF-2 cranks are Promax’s top-of-the-line crank offering. Hollow-forged from 6061-T6 aluminum, both crank arms are hollow so they are super stiff, yet lightweight. The crank arms spin on a beefy 24-millimeter spindle permanently fitted into the drive-side arm.

With a 104-millimeter BCD four-bolt spider, they come in a variety of beautiful anodized finishes.

Meets or exceeds ENBMX standards.

The BB is either BB30 or, when used with the included sleeve, PF30 compatible. For more information about the Praxis M35 bottom bracket, go to:
